Multicolored city

During the demonstration of the 3D-printed model of San Francisco, a group of visual cues were projected onto it, showing how the model could be used to signify demographic or political differentiations, as represented by colors.

Transbay development

One of the key value propositions of the model is that it can be lit up to highlight many different projects, neighborhoods, or even individual buildings. Here we see the Transbay Transit Center development project, a major infrastructure upgrade, that is currently under way and expected to be finished by 2017.

Before and after models

On the right is an unfinished prototype, while on the left is a finished prototype. The difference is that the before piece has not yet been brushed clean to remove the outer layer of resin left by the 3D printer.

Old freeway routes

Longtime San Francisco residents remember the Embarcadero freeway, which came off the Bay Bridge and ran along the city's eastern waterfront. After 1989's devastating Loma Prieta earthquake, the freeway, and others in the city, were demolished. The red pathways on the model show where those roadways used to be.
